| Abstract: |
| 【Objective】in order to study the current situation, summarize experience and find out some problems of high efficiency water-saving irrigation project in Wuwei District of Shiyang River Basin.【Method】The author adopted analytic hierarchy process and fuzzy mathematics methods to set up the evaluation index system of regional comprehensive benefits of high efficiency water-saving irrigation project in Wuwei District of Shiyang River Basin, combining the region characteristics, climate characteristics, water resources characteristics, economic and social development characteristics of Wuwei region and the multi-level linkage coupling effect of city, county, farm and farmer. Choosing economic social ecological coupling benefit as regional comprehensive benefit. The actual survey data are substituted into the index system, and the membership degree and other evaluation results are obtained.【Result】The results showed that the ecological benefits are most significant, it"s level I (corresponding membership values are 0.629), the economic benefits are also level I, and it"s membership value is 0.508; the social benefits are level II and the regional comprehensive benefits are level I. But the degree of conformity to the adjustment of regional agricultural structure (C22) is relatively low, which is class III. 【Conclusion】The ecological and economic benefits of the high-efficiency water-saving irrigation project in Wuwei District of Shiyang River Basin are significant; In the future, we should increase the intensity of land transfer, promote the optimization and adjustment of crop planting structure by planting large households, Cultivate the endogenous demand power for efficient water-saving irrigation projects, improve the potential and sustainability of agricultural water-saving, and further consolidate social benefits. |
